单独安装hive
使用Derby数据库的安装方式
什么是Derby安装方式
•Apache Derby是一个完全用java编写的数据库,所以可以跨平台,但需要在JVM中运行
•Derby是一个Open source的产品,基于Apache License 2.0分发
•即将元数据存储在Derby数据库中,也是Hive默认的安装方式
安装Hive
•解压Hive
1. tar zxvf hive-0.8.1.tar /home/test/Desktop
•建立软连接
1. ln –s hive-0.8.1 hive
•添加环境变量
1. •export HIVE_HOME=/home/test/Desktop/hive
2. •export PATH=….HIVE_HOME/bin:$PATH:.
配置Hive
•进入hive/conf目录
•依据hive-env.sh.template,创建hive-env.sh文件
1. cp hive-env.sh.template hive-env.sh
•修改hive-env.sh
•指定hive配置文件的路径
1. export HIVE_CONF_DIR=/home/test/Desktop/hive/conf
•指定Hadoop路径
1. HADOOP_HOME=/home/test/Desktop/hadoop
